year 11 Physics  next 50 years or so, so i should still be alive. |
Not the next 50 years, it doesnt just happen like switching on a light bulb, it happens gradually over a long period of time.
I think the last time it happened was about 10000 years ago, or something daft, so we are definately due for one, it may even be happening now. |
Seems to be constantly shifting according to this:

Nasa saying the last flip indicated by the magnetism in rocks was 780,000 years ago with them happening every 300,000 on average.
I do like this idea though:

A south magnetic pole might emerge over Africa, for instance, or a north pole over Tahiti. Weird. But it's still a planetary magnetic field, and it still protects us from space radiation and solar storms.
And, as a bonus, Tahiti could be a great place to see the Northern Lights.
